Black Carbon (BC) and combustion-derived Polycyclic Aromatic Hydrocarbons (PAHs), as inert products of combustion, serve as indicators of palaeo-wildfire for their long-lasting preservation in the sediments. Recently, wildfire records including BC particles and combustion-derived PAHs were discovered in the PermianTriassic (P-Tr) sediments worldwide. It is especially exciting that the content of BC and combustion-derived PAHs in the Meishan P-Tr boundary shows steep peak coinciding with the mass extinction horizon (bed 25 and bed 26). Thus, the P-Tr wildfire event was definitely proposed for the first time. It is deserved to probe the scale and characteristics of the P-Tr wildfire, and the relationship between wildfire and mass extinction. Wildfire, which  occurs on land, could tie land, atmosphere and ocean together through combustion products. Climatic and environmental changes, as a result, can be studied by wildfire which gives a holistic approach to understanding the catastrophic history. Therefore, wildfire records in the P-Tr sediment were reviewed, and the relationships between wildfire and mass extinction were appraised in order to draw experts′ attentions.
